% Plot a graph defined by @var{A} and @var{xy} in the graph theory
% sense. @var{A} is the adjacency matrix of the array to be plotted
% and @var{xy} is an @var{n}-by-2 matrix containing the coordinates of
% the nodes of the graph.
%
% The optional parameter @var{line_style} defines the output style for
% the plot. Called with no output arguments the graph is plotted
% directly. Otherwise, return the coordinates of the plot in @var{x}
% and @var{y}.
